Tol all whom fit maiy'.ron-c er'lt.'4 I 'Be it known that I, CLEMENT.

at Maplewoodlldissouri; have' invented a certaln new' and useful `which'the-ollowingis a 1111, clear, andl exact description, such as 'will enable others skilled the artto which it appertain'stoA make and the same, reference beinghad to the ac' "companying dra specification,

particularly to the, mechanism employed in' This invention relates to dumpears, and

,such cars foractuating the doors W ichclose A the discharge openingsin the body of the car. i

The main-object of my invention is 'to provide a door-operatin mechanism of simple constructionthat wil positively control the movements of the door with which it is used and which will not be apt tofjam or get out of order quickly.

Another object of my invention is to providea car -door-operating mechanism that can be manufactured at a 4small cost and which comprisesjfew parts and does not pro'- ject laterally beyond thegsidesof the car.-

' illustrate the preferred form-of my invention, `1 designates a drop door that closes a discharge opening in the bottom of the car, said door being hinged atits .inner -end adjacent the center sills of the car and having its outer edge 'extending parallel `to -and contacting Withan angle 2 securedrto the lower edge of .theplate girder side wall 3 of thecar.

Each of the actuating bars 5 is provided at its lower endwith an inwardly-projecting arm 6, preferably.disposed at ap roximately allcute angle relatively to the h of these arms have a sliding connectionwith thedr'opjdoor 1; I prefer to form the arm 6v integraIwith the bar 5 and stren then it ar and the inner ends y at .the point Where it curvesupwar y vfrom the bar by means of ribs 7, the bar. 5 and 6. both beigsubstantially I-shaped lin cross ,i

section.. The door '1. is'preferably formed of pressed metal and is provided with an inte-v `gral downwardly projecting` ilange la' and 'the portion of theflange at the outer edge oi the door is cut awayA to provide a clearance for the arms 6 of the actuating bars, twovo'f said actuatin door. 'Box-shaped metal members,- 8v are secured. to the underneath side of the door Walls 'of said members are provided With elongated slots 9 that receive cross pins 10 vin the arms (ii,v as shown in Fig. 2 each of saidpins bein provided with a roller I11 that' aetween jaws on`the inner endof arranged the arm 6.

.Each of the bars 5 is provided onits inner face with rackteeth that coperat'e with a pinion 12 on an operating shaft 13 arranged ongitudinally of the car, said shaft'being .journaled in bearings 14 that are fastened to the angle 2 'on the lower edge of the plate girder side wall I also preferto provide the 'arms 6 on their upper sides with. side lianges 6a that partiallyincase the pinions 12`when the door is closed, said flanges merging-into 'the bars 5 and thus strengthening. f

the arms. A handle or other suitable'device,

not shown, may be connected to the operata:

bars being rovided adjacent their upper ends with s oulders or cross webs 16 that tive connection between the l the door and the arms 6.

contact with the stops 15 and thus limit the downward `movement `of the bars. When the contents of the car is to be discharged the yoperating shaft is turned so as to move the actuating bars downwardly and thus open the door, the pins 10 in the arms 6 sliding in the eilengated slots 9 in the members on thedoor and thus providing a sliding connection between To close the door the operating shaft is rotated in the reverse direction thereby moving the actuating bars upwardly and thus returning the door to the position shown in full lines in Fig. 2.
